Abstract

This study presents the experimental investigation on performance testing of a parabolic trough solar collector (PTSC) array consisting of three modules connected in series. A new test setup has been proposed to test the thermal performance of this PTSC array in compliance with ASHRAE 93-1986 standard. The experimental tests have been carried out and monitored in a number of days under cloudless sky conditions in Gaziantep. In the performance analyses, the effects of beam radiation, collector inlet temperature, ambient conditions, and the variation in mass flow rate of the working fluid were investigated. The steady-state and dynamic tests of the PTSC array were performed. The efficiency tests were conducted with thermal oil for the temperature range from 50 °C to 200 °C, and mass flow rate of 0.1 kg/s to 0.5 kg/s under steady conditions. Additionally, the experimental results were compared with the results of the theoretical study made previously and gave good coherency.

Özet

Bu çalışma, seri bağlanmış üç modülden oluşan bir parabolik oluk güneş kolektör (POGK) ağının performans testinin deneysel olarak incelenmesini sunmaktadır. Bu POGK ağının ısıl performansının ASHRAE 93-1986 standardına uygun olarak test edilmesi için yeni bir test düzeneği önerilmiştir. Deneysel testler, Gaziantep'te bulutsuz gökyüzü koşulları altında uygulanmış ve birkaç gün boyunca izlenmiştir. Performans analizlerinde, direk ışınım, kolektör giriş sıcaklığı, ortam koşulları ve çalışma akışkanının kütlesel akış debisinin etkileri araştırılmıştır. POGK ağının daimi-durum ve dinamik testleri gerçekleştirilmiştir. Verimlilik testleri, termal yağ kullanılarak daimi koşullar altında 50 °C ila 200 °C sıcaklık aralığı ve 0,1 kg/s ila 0,5 kg/s kütlesel debi aralığı için gerçekleştirilmiştir. Ayrıca, deney sonuçları daha önce yapılan teorik çalışma sonuçlarıyla karşılaştırılmış ve iyi tutarlılık göstermiştir.
